Alan Charles Ingram Lock (born September 10, 1962 in Marandellas, Mashonaland) is a former Zimbabwean cricketer who played one Test and 8 ODIs. In his only Test match of his career, he has the match figure of 5/105 against South Africa at Harare in 1995. Six of his eight ODIs were in the 1996 World Cup. His best ODI figure of 8.1-0-44-5 came against New Zealand at McLean Park, Napier in 1996.

Lock came to the attention of the world's media in early October 2007 when, as one of the remaining few hundred white farmers in Zimbabwe, he was driven off his land in the Headlands District, some 90 miles (140 km) south-east of Harare. Lock had previously given over a 5,000-acre (20 km²) farm to the government for resettlement and had consequently received permission in 2003 to stay on a small parcel of land, Karori Farm. However, Karori later came to the attention of General Justin Mujaji, whose soldiers evicted Mr Lock together with the farm's 158 labourers and their families so that he could take over the property for himself, together with his wife, Pauline.

Lock brought a contempt of court application against General Mujaji and his wife, but the General said that he would stay whatever the legal ruling, and commenting "I will only leave Karori if the minister of lands orders me. He is senior to the courts."
